As an archaeologist with the new Cheap Jerseys From China , Paleolithic to divide the two stages of human prehistory, and today we can turn in two chemical elements to describe the materials revolution is taking place.
The last decades of the 20th century is the era of silicon, oncoming, it is the era of carbon materials.
The 20th century, whether it is represented by silicate glass and cement building materials, silicon-based integrated circuit or a busy single crystal silicon or polycrystalline silicon photovoltaic solar energy components, is behind the appearance of wide range of silicon.
The 21st century Cheap Jerseys China , led by the emerging carbon material system is showing itself more and more potential impact of a challenging industry. If global climate change and to think about the relationship between carbon and low carbon represents more than just a physical and chemical processes, and its profound meaning of aspects of human society, even to decide the fate of the height of human beings.
Not only in China. Materials in the field of aviation, Airbus 320,380, 787 are extensive use of carbon-based composites as structural materials within the aircraft, to achieve the aircraft's own weight Cheap Jerseys , the corresponding process is to reduce the fuel consumption of the flight, the flight to achieve a more green .
Of particular concern is the world represented by BMW electric car manufacturer, carbon fiber composite electric car enthusiasm. 2012 BMW has announced production of carbon composite materials for electric cars, and has invested heavily in the United States set up the production of carbon fiber manufacturers, established in Germany, and forming the corresponding fiber weaving company. Foreseeable future, electric cars will be the mainstream a lot of carbon composite materials. Other applications of carbon fiber include wind power blades.
If you take into account traditional silicon-based materials such as cement Wholesale Jerseys Free Shipping , glass and steel industry from mining to finished product contamination and the process of comprehensive energy consumption, carbon materials, the advantage is even more evident.
Of course, the traditional materials of interest will be the beneficiaries of the chain to refute a variety of reasons cited to defend himself, to high-end aircraft engines, for example, today Wholesale Jerseys China , driven aircraft to jet fuel, whether or turbofan engine turbojet will face new order solar and other clean energy for the electric or magnetic drive on behalf of the challenges of the aircraft, just as today's new motor vehicle engines are being substituted. Support the key mainstream aircraft engine material inevitably turned to a new generation of structural materials system. Is the arrival of a new generation of photovoltaic materials, but also to carbon-based organic photovoltaic materials such as thin film materials, the use of quantum effects to improve the energy conversion efficiency. Unfortunately, due to the current mainstream of the photovoltaic material because they do not consider the environmental costs of the vicious competition, price is too low Wholesale Sports Jerseys , resulting in delays in new optical materials available, and even forced to cancel the production plan, leaving only R & D capabilities.
Sound is always a moment, scientific innovation is long. Carbon fiber has started in the aviation, automotive and other fields to replace steel. Even more interesting is, aircraft and ground vehicles using carbon fiber composite materials, although for c
